yes.



Yes, the benefit is from the greater adjustability of the frac. rig.


lots of advantages to a frac rig, but suppression of the tip vortex of

the jib

is not one of them.


Shh, it'll take Doug quite some time to figure this all out.



MC,

I'm usually quite lost (at sea) during your discussions with Doug.
However, I never expected to see you depend on Jax for support. Well,
now I know!


You miss the point. Jax is correct on this one and I am giving him
credit for that. Just 'cos he's Jax doesn't mean he's always wrong!

Cheers

He'll take whatever he can get, first it was Bubbles tremendous
expertise he relied on, now it's Jax.

But he did not answer either question meaningfully.

what word didn't you understand, dougie?

you asked a question, and yes or no were the correct answers.

as far as investment advice goes I can only repeat the advice of Will Rogers.
"Buy and when the stock goes up, sell. If it doesn't go up, don't buy".

If that is true (seems unlikely in view of your knowledge level) then
please explain why.

dougie, the tip vortex comes about because the pressure on the windward side of
the sail is greater than on the leeward side. The greater pressure tries to
make it to the lower pressure. the air on the heavy side rolls over the aft
edge of the sail in the easiest possible manner, which includes going up as
well as back. This makes for the vortex as the aft edge of the sail meets the
forward edge.

having a main sail downwind of the jib does not cause the jib airflow to stop
trying to go from high pressure to low pressure. The vortex generated causes
turbulant air from the jib to screw up the airflow across the main. moving the
top of the jib lower than top of the main just causes the jib vortex to hit
more of the main.

okay?
